LIBNAME libref

LIBNAME libref | _ALL_ CLEAR;
LIBNAME libref | _ALL_ LIST;
Details
The LIBNAME statement can be used to assign a SAS data library, release a library
assignment, or display a list of all library assignments. The LIBNAME function
provides similar functionality. See “LIBNAME Function” on page 268 for more
information.
Assigning a Library The LIBNAME statement allows you to identify a data library to
SAS, specify which engine SAS should use to process the library, and identify the z/OS
resources required to process the library. For a complete discussion of assigning
libraries, see “Assigning SAS Data Libraries” on page 53. For direct or sequential access
bound libraries, the LIBNAME statement can be used to specify the options necessary
to allocate the library data set. For detailed information about z/OS allocation as it
relates to SAS data libraries, see “Allocating the Library Data Set” on page 53.
LIBNAME Statement Forms for Assigning Libraries
The form of the LIBNAME statement used to assign a SAS data library is described
below. See “Examples of Assigning a Library” on page 399 for more information.
LIBNAME libref ;
LIBNAME libref
;
libref
is a SAS name that identifies the library. The libref can be a maximum of eight
characters. The first character must be a letter (A–Z) or an underscore. The
remaining characters can be any of these characters or numerals 0–9. This libref
is used to reference the library throughout SAS.
If the libref specified is already assigned, SAS deassigns the libref before
performing the assignment specified.
Note: SAS System 9 for z/OS supports libref names that begin with or contain
underscores. For example, libref names with formats such as libref_name,
_librefname, or _libref_name are now supported.
Unlike filerefs, librefs cannot include the special characters $, @, and #. R
engine
specifies which engine to use to access the SAS data library.
For a list of some of the native library engines that can be specified on the
LIBNAME statement, see “SAS Library Engines” on page 36. For general
information about these and other engines, see “SAS Engines” in SAS Language
Reference: Concepts.
It is generally necessary to specify the engine only when creating a library that
will be processed by an engine other than the default engine that is indicated by
